步骤S206,将确定后的该子网目标广播波束权值集合发送至该第一子网,其中,该子网目标广播波束权值集合用于指示该第一子网中的成员小区根据该子网目标广播波束权值集合中对应的该成员目标广播波束权值发送广播波束。
通过上述步骤,由于将多个小区划分为一个或多个子网,根据小区覆盖和/或小区间干扰确定任意一个子网的目标广播波束权值,因此,可以解决相关技术中网优效率较低的问题,达到提高网优效率的效果。
可选地,该对于该一个或多个子网中的任意一个第一子网,根据该第一子网所包括的成员小区的小区覆盖在该成员小区的预设权值中确定该第一子网的子网目标广播波束权值集合,包括:对于该第一子网所包括的每一个成员小区,根据每一个该成员小区的终端的参考信号接收功率从每一个该成员小区的预设权值中确定每一个该成员小区的成员目标广播波束权值,将每一个该成员小区的该成员目标广播波束权值组合为该子网目标广播波束权值集合。其中,任一个成员小区的成员目标广播波束权值所对应的小区覆盖高于该任一个成员小区的预设权值中除该成员目标广播波束权值之外的其他预设权值所对应的小区覆盖;或者,

根据该第一子网所包括的每一个该成员小区内的终端在成员备选广播波束权值条件下的信号与干扰加噪声比从每一个该成员小区的该成员备选广播波束权值中确定该子网目标广播波束权值集合,其中,该子网目标广播波束权值集合所对应的小区间干扰小于其他子网广播波束权值集合所对应的小区间干扰,该其他子网广播波束权值为每一个成员小区的该成员备选广播波束权值中除该成员目标广播波束权值之外的其他成员备选广播波束权值所组成的子网广播波束权值。
在一实施例中,示例性地,小区覆盖可以根据小区的信号接收参数(例如参考信号接收功率)确定或者表征,小区间的干扰可以通过信号质量参数(例如信号与干扰加噪声比)确定或者表征。
在一实施例中,分割后得到的子网中,每个子网可能包括一个或多个成员小区,其中,有的成员小区可能没有邻区,例如一个小区可以独自构成一个子网并且该小区也没有邻区的情况。对于没有邻区的成员小区,示例性地,可以只根据成员小区内的终端的信号接收参数确定该成员小区的目标广播波束权值,例如上述的方法。
在一实施例中,如果子网中包括了多个成员小区,那么这些成员小区都是存在至少一个邻区的,对于有邻区的成员小区,示例性地,可以根据成员小区内的终端的信号接收参数和该成员小区的信号质量参数确定该成员小区所在子网的子网目标广播波束权值。对于有邻区的成员小区,在进行网优时,既要考虑小区覆盖,又要考虑小区间的干扰,所以可以根据该成员小区内的终端的信号接收参数和该成员小区的信号质量参数确定子网目标广播波束权值。
可选地,该对于该第一子网所包括的每一个成员小区,根据每一个该成员小区的终端的参考信号接收功率从每一个该成员小区的预设权值中确定每一个该成员小区的成员目标广播波束权值,包括:

对于该成员小区中的每一个预设权值,将该预设权值所对应的所有该服务小区参考信号接收功率所组成的参考信号接收功率区间划分为第二指定数量的等份;在一实施例中,由于可能会有多个终端将一个成员小区作为自己的服务小区,所以一个成员小区在一个预设权值的条件下会对应多个终端的服务小区参考信号接收功率,这些终端的服务小区参考信号接收功率中,最小值与最大值所构成的区间就是该成员小区在该预设权值条件下的参考信号接收功率区间。第二指定数量可以是10、100或1000等数值。
对于该成员小区中的每一个预设权值,分别确定该每个预设权值所对应的每一个该服务小区参考信号接收功率落入每个该等份的频率,确定频率累计分布为第二指定频率时所对应的最大参考信号接收功率;在一实施例中,第二指定频率可以是0.3~0.6中的任意值,例如0.3、0.4、0.5或0.6等。

可选地,针对每一个成员小区,可以根据该成员小区在已知的权值(例如当前生效的广播波束权值)的条件下所得到的该成员小区的信号参数估计出该成员小区在预设权值中的其他广播波束权值条件下的该成员小区的信号参数,例如,可以根据已经生效的权值所对应的信号参数(可测量或者可计算)估计其他未生效的权值所对应的信号参数。
在一实施例中,该成员小区在当前广播波束权值条件下的信号参数可以是直接测量得到的,也可以是直接处理或者筛选测量得到的一些信号参数所得到的。
在本实施例中,“成员小区内的终端”可以理解为将一个成员小区作为服务小区的终端。由于一个成员小区内的终端可以是一个或多个,所以一个成员小区 会对应一个或多个终端的测量数据,例如对应一个或多个终端测量所得到的参考信号接收功率。
可选地,对于每个成员小区所对应的预设权值中所包括的第一预设权值和第二预设权值,第二预设权值所对应的第一终端的服务小区参考信号接收功率为第一预设权值所对应的该第一终端的服务小区参考信号接收功率与第一天线增益之和,其中,该第一预设权值所对应的该第一终端的该服务小区参考信号接收功率是测量得到的,该第一天线增益是根据该第二预设权值、该第一预设权值和该第一终端的波达方向所确定的。
在一实施例中,新的预设权值所对应的终端的服务小区参考信号接收功率可以是根据已知预设权值所对应的已知终端的服务小区参考信号接收功率估计得到。其中,已知终端的服务小区参考信号接收功率可以是使用已知预设权值发送波束的条件下,该服务小区内的终端测量得到的。

对于该第一子网,在每一轮迭代过程开始之前,对于在上一轮迭代过程中的每一个蚂蚁,确定每一个该蚂蚁所选择的子网广播波束权值集合条件下的终端的信号与干扰加噪声比;
将该第一子网的所有该终端的信号与干扰加噪声比所组成的区间划分为第三指定数量的等份;在一实施例中,一个成员小区内可能有多个终端,每个终端在每个预设权值的条件下都对应了一个“信号与干扰加噪声比”。则第一子网可能对应了多个信号与干扰加噪声比,这些信号与干扰加噪声比中,最小值与最大值所构成的区间就是第一子网的所有该终端的信号与干扰加噪声比所组成的区间。
对于该第一子网,分别确定该终端的信号与干扰加噪声比落入每个该等份的频率,确定频率累计分布为第三指定频率时所对应的最大信号与干扰加噪声比,将该最大信号与干扰加噪声比作为该子网广播波束权值集合所对应的子网信号与干扰加噪声比。第三指定数量可以是10、100或1000等数量。第三指定频率可以是0.3~0.6中的任意数值,例如,可以是0.3、0.4、0.5或0.6等数值。
可选地,该成员小区内的终端的信号与干扰加噪声比为:该终端所在的服务小区的参考信号接收功率,与,该终端所测量得到的该服务小区的邻区的邻区参考信号接收功率之和加白噪声功率,的比。
可选地,对于一个成员小区所对应的成员备选广播波束权值中所包括的第一成员备选广播波束权值和第二成员备选广播波束权值,第一成员备选广播波束权值所对应的第一终端的该邻区参考信号接收功率为第二成员备选广播波束 权值所对应的该第一终端的该邻区参考信号接收功率与第二天线增益之和,其中,该第二成员备选广播波束权值所对应的该第一终端的该邻区参考信号接收功率是该第一终端测量得到的,该第二天线增益是根据该第一成员备选广播波束权值、该第二成员备选广播波束权值和该第一终端的波达方向所确定的。

可选地,该利用蚁群算法从每一个该成员小区的该成员备选广播波束权值中确定该第一子网的该子网目标广播波束权值集合,包括:

达到预设的迭代次数之后,将多个该子网广播波束权值集合中,最大的子网信号与干扰加噪声比所对应的子网广播波束权值集合作为该子网目标广播波束权值集合。在一实施例中,每一轮迭代过程中,每个蚂蚁都选择了一个子网广播波束权值集合,由于每个子网广播波束权值集合对应了一个子网信号与干扰加噪声比,所以每一轮迭代过程中产生了多个子网信号与干扰加噪声比;子网信号与干扰加噪声比越大,则说明该子网广播波束权值集合越优,所以可以选择所有迭代过程中的最大的子网信号与干扰加噪声比所对应的子网广播波束权值集合作为该子网的子网目标广播波束权值集合。
可选地,该第一小区与该第二小区的小区间重叠覆盖程度为第一重叠覆盖度与第二重叠覆盖度的平均值,其中,该第一重叠覆盖度为该第一小区相对于 该第二小区的重叠覆盖度,该第二重叠覆盖度为该第二小区相对于该第一小区的重叠覆盖度。

可选地,按照预设的波束数量和预设的波束下倾角间距确定该成员目标业务波束权值的下倾角。例如,预设的波束下倾角间距为2度或者3度或者4度或者5度等,同一小区的不同的业务波束可以按照相同的下倾角间距连续分布。

可选实施方式
为了使4G LTE/5G NR系统在多样化场景中具有最优覆盖及频谱效率,本实施例提出了4G LTE/5G NR系统中一种自适应调整天线权值的方法。该方法根据用户分布、测量报告(Measurement Report,MR)生成每个小区的同步信号和PBCH块(synchronization signal and PBCH block,SSB)波束权值和信道状态信息参考信号(channel state information reference signal,CSI-RS)波束权值,其中,PBCH的英文全称是Physical Broadcast Channel,中文全称是物理广播信道。
在一实施例中,SSB波束权值相当于一种广播波束权值。CSI-RS波束权值相当于一种业务波束权值。
对于4G LTE/5G NR超密集同频组网的天线权值联合优化,本实施例提供了一种方法,图4是根据本申请可选实施方式的网优方法的流程图,如图4所示, 包括:
在网管侧进行优化区域选择及任务配置,并把任务下发到网元。优化区域可以根据网优人员指定,也可以通过工具自动识别,任务配置选中需要优化的目标,激活任务。
网元进行MR数据收集和到达角(Direction of Arrival,DOA)数据测量,并把数据上报给网管。
网管根据收集的数据进行子网分割和最优权值估算。
网管下发新权值到网元生效,网元进行关键性能指标(Key Performance Indicator,KPI)采集并上报给网管。
网管根据收集的KPI信息进行权值评估,若评估通过,下发权值更新到网元;若评估不通过,下发权值回退到网元。
图5是根据本申请可选实施方式的权值的发送方法的流程图,如图5所示,包括:
开始。
数据收集,例如收集终端上报的测量报告。
子网分割,其中,示例性地,子网分割的过程可以如下:
为了提升蚁群算法的优化效率,根据收集的MR数据进行子网分割,子网分割操作根据MR测量结果计算每个小区和其邻小区的重叠覆盖度,以重叠覆盖度来反映两小区的关联紧密程度,重叠覆盖度越大,则认为关系越紧密,每个子网限定小区个数为CellNumThr,默认50,可配。子网分割步骤如下所示。
可选地,根据以下公式计算小区间重叠覆盖度:
例如由A和B两小区,小区A计算它与小区B的重叠覆盖度方法:
Figure PCTCN2021076147-appb-000001
假设A为服务小区,B为小区A的邻区,记RSRPi为服务小区参考信号接收功率(Reference Signal Receiving Power,RSRP),RSRPj为邻区RSRP:
条件1:RSRPi大于或等于“服务小区覆盖RSRP门限ucOverlapSrvThd”;
条件2:RSRPj大于或等于“邻区重叠覆盖RSRP门限ucOverlapNbrThd”;
条件3:abs(RSRPj-RSRPi)大于或等于“邻区重叠覆盖RSRP差值门限ucOverlapNbrDifferThd”,其中,abs()表示取绝对值。
同样的方法计算小区B与小区A的重叠覆盖度记为C BA,如下:
Figure PCTCN2021076147-appb-000002
其中,假设B为服务小区,A为小区B的邻区,记RSRPi为服务小区RSRP,RSRPj为邻区RSRP:
条件1:RSRPi大于或等于“服务小区覆盖RSRP门限ucOverlapSrvThd”;
条件2:RSRPj大于或等于“邻区重叠覆盖RSRP门限ucOverlapNbrThd”;
条件3:abs(RSRPj-RSRPi)大于或等于“邻区重叠覆盖RSRP差值门限ucOverlapNbrDifferThd”,其中,abs()表示取绝对值;
最终得到小区A和小区B的关联程度:
Figure PCTCN2021076147-appb-000003
基于以上方法,可以根据用户设备(User Equipment,UE)数据计算出多个小区间的关联关系。假如有15个小区A~O,则可以构成如图6所示的加权连通图,图6是根据本申请可选实施方式的加权连通图,图6的边即是两小区的关联程度。
然后,根据小区加权连通图,通过普里姆算法生成子网。可选地,可以通过不断提高小区加权连通图中的不同小区之间的关联程度的熔断门限生成最大生成树,方式如下:
子网的分割方法,基本原则是将联系紧密的小区划分到一个子集,可以采用图论中的普里姆算法先求得最大生成树,最大生成树能保证所有小区依然处于连通状态,然后再基于最大生成树进行分割,普里姆求解最大生成树算法流程如下:
1).输入:一个加权连通图,其中顶点集合为V,边集合为E。
2).初始化:Vnew={x},其中x为集合V中的任一节点(起始点),Enew={},为空;
3).重复下列操作,直到Vnew=V:
a.在集合E中选取权值最大的边<u,v>,其中u为集合Vnew中的元素,而v不在Vnew集合当中,并且v∈V(如果存在有多条满足前述条件即具有相同权值的边,则可任意选取其中之一)。
b.将v加入集合Vnew中,将<u,v>边加入集合Enew中。
4).输出:使用集合Vnew和Enew来描述所得到的最大生成树。
图7是根据本申请可选实施方式的最大生成树示意图,如图7所示,按边权重小于门限(门限可配)的边熔断,例如将权重小于0.2的边熔断,得到了图8中所示的内容,图8是根据本申请可选实施方式的熔断示意图,在图8中,子网内最多包括7个小区,每个子网均满足子网内最多包括9个小区(子网所包括的最多小区数门限可配)的要求。在一实施例中,若实际出现分割后一些子网小区数超过最大小区数要求,则说明熔断门限设置不合理,需要提高熔断门限。由于图7中所述的子网中的小区数量超过了预设的数值(例如可以是9),所以,可以不断提高熔断门限使得分割后的每个子网所包含的小区数小于或等于子网最大小区数门限。
然后,以RSRP CDF50最大化为代价函数遍历得到每个小区TOP N个最优SSB波束权值,其中,CDF(cumulative distribution function)为累积分布函数;然后以信号与干扰加噪声比(Signal to Interference plus Noise Ratio,SINR)CDF50最大化为代价函数通过蚁群算法进行SSB波束权值寻优,示例性地,步骤如下:
对于子网内的每个小区以RSRP CDF50最大化为代价函数通过遍历方法进行SSB波束权值寻优,对于存在邻区关系的小区以SINR CDF50最大化为代价函数通过蚁群算法进行SSB波束权值寻优。本步骤包括以下步骤:
1)子网内每个小区根据用户DOA、MR数据以RSRP CDF50最大化为代价函数,通过遍历方法得到每个小区TOP N个最优权值,RSRP CDF50代价函数计算公式如下所示。
新权值下的UE在服务小区的RSRP基于MR上报的RSRP及新权值下的天 线增益计算得到。假定UEi在权值k对应的MR上报计为RSRPi,k,该UE对应的DOA角度为(h,v),那么在选择新权值j时,该UE的RSRPi,j计算方法如下:
RSRPi,j=RSRPi,k+AntGainTbl[j][h][v]-AntGainTbl[k][h][v]
其中:AntGainTbl为保存的3D天线增益表。
该UE测得邻区RSRP的估计方法相同,该UE在多个邻区的DOA信息由邻区协助测量得到。
把所有UE更新后的RSRP进行从小到大排序,并把RSRP区间分割成1000等份RSRP小区间,统计落入每个RSRP小区间的频率,计算RSRP累积分布为0.5时对应RSRP小区间中最大RSRP值作为代价函数值,通过遍历所有权值,计算每个权值的RSRP CDF50值,取最大的TOP N个权值作为后续SINR CDF50优化时的候选权值。
2)子网内所有小区根据用户DOA、MR数据以SINR CDF50最大化为代价函数,通过蚁群算法得到子网内所有小区联合最优权值。SINR CDF50代价函数计算公式如下所示。
UE SINR计算方法:
Figure PCTCN2021076147-appb-000004
其中:
可选地,服务小区RSRP,邻区RSRP计算公式同步骤1)。
可选地,计算SINR前需要先将RSRP转化为线性值。
可选地,白噪声功率:-174dBm+10*log(30*1000)=-130dBm,考虑UE接收机噪声系数,设定白噪声功率为-125dBm。
可选地,SINR计算需要做最大/最小值保护,-20dB≤SINR≤40dB。
可选地,上述UE SINR的计算方法中的“邻区”指的是每个终端上报的MR测量报告中该终端测量到的所有邻区。
在一实施例中,每个终端在一种权值的条件下对应一个UE SINR,由于一个子网内可能有多个小区,每个小区又对应了多个备选权值,每个小区内又可 能有多个终端,所以,一个子网可以对应多个UE SINR,把一个子网所对应的所有小区内的所有终端的UE SINR进行从小到大排序,并把SINR区间分割成1000等份SINR小区间,统计落入每个SINR小区间的频率,计算SINR累积分布为0.5时对应SINR小区间中最大SINR值作为代价函数值,通过蚁群算法,计算所有小区联合搜索权值,每个小区都从步骤1)得到的候选权值中进行搜索。
图9是蚁群算法的算法流程图,如图9所示,包括:
开始。
初始化参数;其中,需要初始化的参数包括蚂蚁数量m,信息素重要程度因子α,启发函数重要程度因子β,信息素挥发因子ρ,信息素强度系数Q、和最大迭代次数Iter_Max。
构建解空间;以一个子网中包括了4个成员小区为例,则该子网的子网目标广播波束权值的基本解定义如下:
W=[Wcell0,Wcell1,Wcell2,Wcell3]
其中每个小区的权值为选择的N个备选权值之一(即上述的候选权值)。每个小区每个权值的选择概率由如下公式决定:
Figure PCTCN2021076147-appb-000005
其中:
-P i k表示蚂蚁k选择权值i的概率;
i(t)表示t时刻,权值i上的信息素浓度;
i(t)为权值期望值,表示t时刻,权值i的期望程度。
由以上公式可知,权值i的信息素浓度和期望值越高,其被选中的概率越高。期望值η i(t)定义为权值解空间下所有小区下代价函数计算得到的价值,根据搜索目的的不同,η i(t)的处理略有所不同:
Figure PCTCN2021076147-appb-000006
每个权值的选择概率基于每个小区维护的权值-信息素浓度-权值期望表格计算得到,信息素浓度初始值为τ 0,权值期望初始化为η0,每个权值的初始选择概率为1/N(N为备选权值个数)。
表1
权值w 信息素浓度τ i(t) 权值期望η i(t) 概率P
W0 τ 0 η0 1/N
W1 τ 0 η0 1/N
... ... ... ...
WN-2 τ 0 η0 1/N
WN-1 τ 0 η0 1/N
表1是权值-信息素浓度-权值期望表,每个小区都需要维护如上一张的表1,在一实施例中,对于所有蚂蚁,在完成一轮迭代后,其中权值期望是该小区所有选择了该权值的蚂蚁计算得到的代价函数平均值。
权值选择采用俄罗斯轮盘赌的概率选择方式。轮盘上不同颜色块代表不同权值,色块宽窄表征了对应权值的选中概率,色块越宽,选中概率越高。
更新信息素。
蚂蚁在释放信息素的同时,多个权值历史累积的信息素也会逐渐消失。设参数ρ(0<ρ<1)表示信息素的挥发程度。因此当所有蚂蚁完成一次搜索后,需要对每个小区的每个权值的信息素浓度进行更新,更新公式如下:
Figure PCTCN2021076147-appb-000007
其中,Δτ k表示第k只蚂蚁在该权值上释放的信息素浓度,若该蚂蚁本次迭代未选择该权值,则其释放的信息素浓度为0;Δτ表示所有蚂蚁在该权值释放的信息素浓度之和。一个权值被蚂蚁选中的越多,其信息素浓度越大。
蚂蚁释放的信息素问题,使用ant cycle system模型,该模型中,Δτ k的计算公式如下:
Figure PCTCN2021076147-appb-000008
其中:Q为常数,表示信息素增加强度系数,该参数取值一定程度上决定了算法的收敛速度,η由价值函数决定。η越大,UE释放的信息素浓度也越高。
本实施例中,首先以RSRP CDF50为代价函数搜索一次权值保留top N个权值用于后续联合优化,这一步可以保证每个小区最优覆盖,然后以SINR CDF50最大化为代价函数联合搜索是为了保证小区间干扰最小。
然后开始迭代,在迭代次数达到预设的最大迭代次数的情况下,停止继续迭代,输出最优解,然后结束算法过程。
可选地,还可以利用每个小区最优SSB波束权值的方位角和倾角联动调整CSI-RS波束权值,在一实施例中,利用最优广播波束信息联动调整业务波束,不仅可以同时调整广播波束与业务波束,还可以避免单独调整业务波束带来的计算开销。其中,示例性地,业务波束可以设为4波束,4波束的水平波宽都固定为50度,垂直波宽都固定为6度;业务波束的方位角取每个SSB的合成方向图(Pattern)的方位角(Azimuth);业务波束的下倾角度根据SSB Beam tilt调整,规则表如下表2:
表2
SSB_Tilt CSI0_Tilt CSI1_Tilt CSI2_Tilt CSI3_Tilt
-3 -3 0 3 6
0 -3 0 3 6
3 0 3 6 9
6 3 6 9 12
9 3 6 9 12
12 6 9 12 15
举例说明:若优化后最优SSB波束权值为方位角20度,下倾角3度,水平波宽45度,垂直波宽7度,则对应的CSI-RS 4个波束权值分别为CSI_beam0方位角20度,下倾角0度,水平波宽50度,垂直波宽6度;CSI_beam1方位角20度,下倾角3度,水平波宽50度,垂直波宽6度;CSI_beam2方位角20度,下倾角6度,水平波宽50度,垂直波宽6度;CSI_beam3方位角20度,下倾角9度,水平波宽50度,垂直波宽6度。
然后把所有子网优化后的权值进行拼接,然后下发权值生效。权值拼接按照子网ID从小到大,子网内按照基站ID,小区ID从小到大顺序进行权值组合。
然后新权值下发后,对每个子网分别进行KPI评估,若评估通过,进行权值更新;若评估不通过,进行权值回退。
KPI包括:基础KPI和性能KPI;基础KPI包括:RRC连接建立成功率,系统内切换出成功率,无线掉线率等。性能KPI包括:频谱效率(Spectral Efficiency,SE),平均激活用户数等。
KPI评估按照如下规则进行评估:
区域指标评估:
任务中所有小区在优化前“评估时长”的平均指标=kbase,
优化后所有小区在优化后“评估时长”的平均指标=kopt,
满足:满足1,指标分=0;满足2或4,指标分=1;满足3,指标分=-1,
1.kbase*(1-波动门限)<=kopt<=kbase*(1+波动门限)
2.kopt>kbase*(1+波动门限)
3.kopt<kbase*(1-波动门限)
4.kopt>=绝对门限
所有指标分的和>=0,区域级指标评估通过,所有指标分的和<0,区域级评估未通过。
2)小区级指标评估:
单小区优化前“评估时长”的平均指标=kbase_cell,
单小区优化后“评估时长”的平均指标=kopt_cell,
满足:满足1,指标分=0;满足2或4,指标分=1;满足3,指标分=-1,
1.kbase_cell*(1-波动门限)<=kopt_cell<=kbase_cell*(1+波动门限)
2.kopt_cell>kbase_cell*(1+波动门限)
3.kopt_cell<kbase_cell*(1-波动门限)
4.kopt_cell>=绝对门限
所有指标分的和>=0,该小区的小区级指标评估通过,所有指标分的和<0,该小区的小区级评估未通过。
所有小区的指标通过,则小区级指标评估通过,否则小区级指标评估未通过。
